I'm finally getting around to doing my first steps with Hibachi.
I am using a GNAT toolchain.

I am trying to tell Hibachi about project dependencies, i.e.
I would like to set up the Ada sourcecode search path.
I tried adding the required projects in
"Project" -> "Properties" -> "Project References"
but that did not seem to have any effect (the added projects
do not appear in the switches passed to gnatmake/gcc.)
I'm not sure: Is Hibachi expecting me to specify these directories
in the GPR file?

As a workaround, I'm setting the ADA_INCLUDE_PATH environment
variable. But that is outside of Eclipse, and I'm hoping to find a
mechanism within Eclipse for this.
